- W564008145 abstract "In recent times, among the major problems in oil palm plantation is the lackof proper interpretation of yield maps for site-specific management, theidentification, and understanding of the causal factors influencing thevariability of oil palm yields. The ability to find and comprehend the leaffactors influencing yield variability of oil palm will help in managing theplantation efficiently for better yield. The study of Spatial Varibility of Oil PalmLeaf Nutrients and Yield was carried out at Dusun Durian Estate, GoldenHope Plantations Berhad, Banting, Selangor, in a 15 ha plot which was acoastal oil palm plantation. The objective of this study was to obtain accurateand timely information about the spatial distribution and status of nutrients inthe leaf tissue using Geographic Information System (GIs) for precisionfarming of oil palm plantation. Collection of leaf tissue data were conductedusing systematic sampling and an AgGPS Trimble was used to precisely determine the sampling locations. Geostatistics (GS+) software andclassical statistics were used for data analysis. Leaf nutrient analysisillustrated that the leaf nutrient variability of N, P, K, Ca and Mg from year2000 to 2003 could be classified as low whereas coefficient of variation (CV)values of 2.0 to 2.2, 1.9 to 3.0 and 1.9 to 5.3, 5.7 to 7.4 and 6.6 to 7.4respectively. Based on the semivariance analysis, leaves nutrients have amoderately spatial dependence with the lag distances of 31 1 to 314 m, 161to 249 m, 185 to 311 m and 169 to 314 m for N, P, K and Ca, respectively.Meanwhile, Mg have a strong spatial dependence (S) with the lag distance is94 to 183 m. The variability of fresh fruit bunch (ffb) is moderate and ismoderately spatial dependence with the lag distance of 310 to 314 m. Thereis a strong relationship between FFB yield, N and P in leaf tissue. This resultimplies that N and P in leaf tissue can be used to determine the FFB yields." @default.
